I intend to travel to Chengdu sometime mid-Oct 2010. One of the spot i am interested in is Hailuogou - the place where low-altitude glaciers exist together with hot spring.

Can anyone please help on the following queries:
What is the suggested mode of transport from Chengdu to the town Moxi? And what is the duration of travel between these places?
Is it easy to find accommodation in Moxi or do i have to pre-book(online)?
Is it possible to arrange this trip on my own or would it be easier to go through an agent?
